Hello Matt,

there is no need to use FQDN for the Sympa email domain.

The Sympa email domain should be dedicated and not shared with other 
accounts, so you
often end up with something like sympa.something.edu or lists.something.edu.

Some generic advices on running a mail server:

 - Mailserver needs an MX record
 - Reverse DNS record (PTR) which is not a boilerplate one
 - Domain name resolves to mail server's IP
 - HELO needs sane hostname too
 - SPF for all domains and subdomains
 - DKIM for all domains and subdomains
